FLUSHING APPARATUS'.

SPECIFICATION forming part of Letters Patent No. 692,61 1, dated February 4, 17902. Application filed August 29, 1901. Serial No.73 ,741. (No model.)

To all whom it may concern,.-

Be it known that I, JOHN BURGUM, engineer, a subject of the King of Great Britain, residing at 43 Rua do Rozario, in the city of Rio Janeiro, in the Republic of Brazil, have invented certain new and useful Improvements in Flushing Apparatus, of which the following is a specification'.

This invention relates to a flushing apparatus; and the objects and advantages thereof will be set forth in the following description, while its novelty-will form the basis of the claims appended to said description.

The invention is clearly represented in the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a longitudinal sectional elevation of a flushing apparatus including my improvements, the section being in the line a b, Fig. 2. Fig. 2 is a plan view of the same. Fig. 3 is'a sectional elevation of a modified form of float and certain adjacent parts, and Fig. 4 is a similar viewofa modified form of valve mechanism.

1 Like characters refer to like parts in all the figures.

On reference toFigs. 1 and 2the letter A indicates a tank of suitable form, and B the valve mechanism, the latter having a suitable valve, hereinafter described, for controlling the supply of water to said tank. The numeral l indicates a supply-pi pe, it having a seat 2 for the valve 3, the valve having a rubber .packing 4, adapted to bear against the seat 2 to shut off the supply of water. The valve is actuated by the lever 5, fulcrumed, as at 6, at one end thereof inside the tank and pivoted, as at 8, to the lug 7.on

the float C. The outer end of the lever is of inverted-U shape, as at 12, the left branch or leg of the U being denoted by 11 and guided by lugs 11 on the outside of the tank. The lower end 9 of the branch'll has connected therewith the pull-chain 10. When the chain is pulled down, the U-shaped portion 12 of the lever 5 is caused to straddle the left wall of the tank until the upper end of saidl U-shaped portion strikes said wall, the further motion of the lever being thereby limited. The float C includes a suitable casing, as 13, the head 14 of which is convexed on its upper face, such head carrying the lug 7 ,to which reference has been made. Through the flat bottom 15 of the casing 13 the pipes 16 pass, their opposite ends being open. Said bottom 15 Vhas a central discharge-orifice 17 with a downturned flange 18, having a pean annular seat to receive the correspondingly-shaped flange 22 at the upper end of the pipe-section 23, externally threaded and passing through a perforation in the bottom of the tank A. The pipe-section 23 below the tank receives the nut 25, by turning which the flange 22 is caused to bind the lower end ofthe bellows-tube against the bottom ofthe tank A, so as to provide an absolute watertight joint at this place. is tapered inwardly, as at 28, at its lowerend to receivet-he flared upper end 29 of the discharge-pipe 27, which is usually made of-lead,

.and the joint between these parts is encircledy by the nut 31, the lower portion 30 ofwhich The pipe-section 23 r tapers inwardly, andby tightening said nut i the pipe 27 is brought by a wedging action into firm contact with the pipe-section 23, so as to provide a close joint.

It will-be assumed that the tank A is filled with water and'that the parts are in the positions shown in Fig. 1. When/the chain 10 is pulled downwardly, the lever 5 and float C will be caused to move in correspondence therewith, therebycompressing the bellowstube D, so that the water in the tank A can be siphoned through the pipes 16, casing 13,

tube D, pipe-section 23, and pipe 27 to flush a closet or the like. The lever being down the valve 3 will be opened andthe incoming water will cause the float O to rise and extend the bellows-tubeD, suchoperation continuing until all the parts are returned to their primary positions with the valve 3 wholly closed.

I will now describe a means employedfor v effecting the automatic discharge of the tank A at desired intervals.

Referring to Fig. 3, the letter Findicates an auxiliary siphon, including a tube 32,soldered or otherwise fastened in the orifice and closed by a circular cap 33, presenting acentral oritice 34, constitutinga part of the straight tube 35 and having the tube 36, the several parts being suitably secured in place, for example, by means ot' solder. For automatic discharges the supply-pipe 1 has a small orifice 40, which is controlled by the pointed end of the needlevalve 42 intersecting the pipe, the valve being held in place by being tapped into said pipe. When the needle-valve 42 is open, the water can flow from the pipe 1, notwithstanding the fact that the valve 3 is closed, and with the float C in its highest position the water when it passes above its normal level enters the casing 13 through the main Siphontubes 16 and falls onto the bottom of said casing, thereby causing said iioat to sink and compressing the tube D and securing the discharge of the Water from the tankA and subsequently the discharge of water in the casing 13 through the auxiliary Siphon. When the water in the casing 13 has passed therefrom, the fioat rises, andthe operation -is subsequently repeated.

Having described the invention, what I claim is 1. The combination ofa tank having an outlet, a bellows-tube the lower end of which is connected with said outlet, a float having an outlet in its bottom centrally thereof connected with the upper end of said tube, and a siphon-tube'projecting through the bottom of said float at one side of the outlet in said float.

2. The combination of a tank having anfoutlet, a bellows-tube the lower end of which is connected with said outlet, a float having an outlet in its bottom centrally thereof connected with the upper end of said tube, a siphontube projecting through the bottom of said float at one side of the outlet in said iioat, a

supply-pipe for said tank, having a valve, and a lever for actuating said valve connected with the iioat.

3. The combination ofa tank having an outlet, a bellows-tube the lower end of which is connected with said outlet, a float having au outlet in its bottom centrally thereof connected with the upper end of said tube, siphontubes projecting through the bottom of said float at opposite sides of the outlet in said eeae oat, a supply-pipe having a valve, and a le- 5o ver for actuating the valve, said lever being pivoted to the upper side of the float and having an inverted-U-shaped portion.

4. The combination of a tank, a float in said tank having an outlet provided with a downturned peripherally-grooved annular iiange, a bellows-tube provided at its top with an annulus iitted in the groove in said flange, a pipe-section projecting through the bottom of the tank and having a flange set in a seat in the lower end of the bellows-tube, a nut on said pipe-section, a pipe the upper end of which is iared to embrace the lower end of the pipe-section and the latter being tapered, and a tapered nut at the junction of the pipesection and pipe.

5. The combination of a tank, a floatin said tank, a main Siphon-tube projecting into the float through the bottom thereof and having a discharge-orifice, a tube secu red in said orice, a circular cap secured to said tube and haviugacentral discharge-passage, abellowstube connected to the tioat in line with said orifice, and a discharge-outlet in communication with said bellows-tube.

6. The combination of a tank, a tloatin said tank, a main Siphon-tube projecting into the float through the bottom thereof and having a discharge-orifice, a tube secured in said oritice, a circular cap secured to said tube and having a central discharge-passage, a second tube surrounding the other tube and separated therefrom and also inclosed by said oritice, a bellows-tube connected to the oat in line with said orifice,- a discharge-outlet in comm uuication with said bellows-tube, a supply-pipe having main and auxiliary valves, the auxiliary valve being hand-operable, and a lever for actuating the main valve, connected with said float.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOHN BURGUM.
